The serial lathe turning & milling work center independently developed by Shenyang Numerically-controlled Machine Tool Co., Ltd. broke through overseas technological monopoly and created well-known brand of high grade compound machine tools in the keen technical competitions for machine manufacture both at home and abroad, and it was the champion in market competitions at home.
Recently the lathe turning and milling work center SSCKZ80A-5 developed by the Company won the bid invited at home by a space power machinery works in Shanxi, and it was the champion from product design to processing behavior. The requirements for processing behavior and process accuracy are quite high in the bidding. The machine is required to be of high flexibility and of such process capabilities in lathe turning, milling, drilling, and boring. All kinds of parts in different complicated shapes and of high accuracy requirements can be completed during one chucking. It is provided with five-shaft and four-linkage functions and it also meets the requirements of high efficiency. The highest speed of rotation of main shaft shall reach 2000 rpm, and that of cutting tool 4000 rpm, and the tool change time is 15s. Furthermore simultaneous movement of two center frames that participates in numerically controlled program needs to be realized. The scope of support according to changes in part diameter can be automatically adjusted to reach high precision and high rigidity of parts processed.
The successful bid indicated that the Numerically-controlled Machine Tool Co., Ltd. has new competitive advantages in the field of high grade products. It will further increase independently innovative capabilities.
